Burst pipes & leaks calculator — FAQs
Turn off the stopcock, then open the cold taps to drain the system. If water is near electrics, switch off at the consumer unit. Take photographs before you clear up — insurers ask for them, and they cost nothing to take.
Most buildings policies cover escape-of-water damage and often 'trace and access' — the cost of finding the leak and making good afterwards. The repair to the failed pipe itself is sometimes excluded. Check your trace-and-access limit before authorising invasive work.
Lag pipework in lofts, garages and against external walls, keep some background heat during cold snaps, and know where your stopcock is and that it turns. Loft pipework is where most winter bursts happen, and lagging costs a few pounds a metre.
Most emergency plumbers aim for 1–4 hours. Isolating the supply yourself buys you time and dramatically reduces the damage bill while you wait.
